ANTISKID APPLIANCE FOR SHOES Filed Dec. 9, 1931 3 Sheets-Sheet 3 I l {ifZZeacZe asfwzz' or Patented Jan. 3, 1933 PATENT OFFICE ETEOCLE'PASQUALI, OF FREEPORT, NEW YORK ANTISKID APPLIANCE FOR SHOES Applicationfiled December This invention appertains to new and useful improvementsin anti-skid attachments for shoes, and the same is an improvement on myco-pending application, Serial No. 556,637, filed August 12, 1931.

An important object of the invention is to provide an anti-skid devicefor shoes wh ch is especially adapted for use in the play ng of golf,hiking or on icy footlng.

Another important object of the invention is to provide an anti-skidattachment for shoes which can be readily applied and dc tached in aquick and convenient manner.

Other important objects and advantages of the invention will becomeapparent to the reader of the following specification.

Referring to the drawings wherein like numerals designate like parts, itcan be seen in Fig. 1, that numeral 5 represents a shoe upper, whilenumerals 6 and 7 represent the sole and heel portions thereof.

For the sole, the calk and fastener assemblies 8 and 9 respectively areemployed in complement with each other and in connection with the singlecalks 1010 which are at the toe portion of the shoe.

As is clearly apparent in Figs. 18 and 19, it can be seen that thesingle calk 10, each includes an outstanding ground engagingprotuberance 11 of hollow construction, and the calk is otherwiseprovided with a hook shaped extension 12 which is engageable over theedge portion of the sole 6 as in the manner substantially shown in Figs.1 and 2.

Diametrically opposite from the hook 12 is a lug extension 13 having anopening 14: therein for receiving one of the links 15. Each of theselinks consists of an elongated metallic strap of spring material, splitand having its ends slightly spaced apart and with one end portiongradually reduced as at 16 to permit ready flexibility when engaging thesame with any one of the fasteners, assemblies, or calks.

Two additional single calks 17-18, are each provided with an outstandingprotuberance 19 and with three laterally disposed tongs 20,each providedwith an opening 21. As is clearly shown in Fig. 2, one of the links 15is interposed between each of the calks 9 1010, and the single calks 18while the calks 17-18 are connected by an additional link 15.

The assembly 8 is connected to the calk 17 bya link 15 while thefastening unit 9 is connected to the calk 17 by a link 15.

- the tab 34.

The calk assembly 8 includes a plate 22 having a slot 23 therein andsuitable weight reducing openings 24 therein. At each end of this plate22, is a calk 25 similar in con struoti-on to the aforementioned calk,and each provided with a sole edge engaging hook 26. Each of these calks25 isequipped with the outstanding protuberance 27 for groundengagement;

The fastener units 9 consist of a U-shaped plate'28 having a calk 29 ateach end of its bight portion, each calk being equipped with theoutstanding protuberance 30 for ground engagement. The leg portions waof this U-shaped plate are each provided with a hinge barrel 7) in itsouter end for receiving the corresponding trunnions 31 of the lever 32.In this manner, the lever is swingably connected .to the U-shaped plateand is preferably of some suitable spring material offset adjacent itsouter end as at 33 to provide a shoulder from which the tab 34-ex tends.

Obviously, with one of the links 15 engaged through the slot 35, of thelever 32, the other inks will serve to draw the calks 1010 and calkassembly 8 as well as the hook 36 on the plate '28 snugly againstthe'edge portion of the shoe sole as the lever 32 is swung downwardlyupon the plate 28. To maintain the prongs in this clamped position, withrespect to the shoe sole, the lever 32 is forced downward upon the plate28 (see Figures 8 and 9) so that the shoulder 33 will engage behind therib 37 and will thus remain in place until separation by the exertion ofpressure against In describing the anti-skid attachment for the heel, itwill be found that numeral 38 represents the forward calk assembly,while numeral 39 generally refers to the rear calk assembly which alsoinvolves the fastening irnezins for clamping both assemblies to the 186Y The assembly. 38 consists of three calk members 39,40 and 41, the calkmembers 39 and 40 being connected to the calk 41 by the reinforced bars42- 42. The calk members39 and 40 are equipped with hooks 43 forengagement with the heel, while the calk member 41 is provided with'atongue 44 having a slot 45 therein for receiving one of theaforementioned linkmembers 15. The aforementioned calks 39, 40 and 41are each provided with a ground engaging protuberance 46.

The calk assembly and fastener 39 consists of a substantially U-shapedplate 47 having a calk 48 ateach end of its bight.

portion, each calk being provided with a ground engaging protuberance 49and also with an obliquely disposed hook member 50 for engagement withthe curved rear portion of the shoe heel 7.

The leg portions CC of the plate 47, is provided with hinge barrels eefor receiving the trunnions 5151 of the lever 52. The lever 52 is ofspring material, is offset as at 53, and at'this point, the same isprovided with a pair of oppositely disposed lateral 3 arms 5454 forengagement over the ribs 5555 on the plate 47. Numeral 56 represents afinger engageable lift, whereby this lever can be removed from thisretained position. It can be seen, that with a link 57 passing thru theopening 58 in the lever 52,
